In demonology Orias is a Great Marquis of Hell, and has thirty legions of
demons under his command. He knows and teaches the virtues of the
stars and the mansions of the planets (the influence of each planet
depending on the astrological sign in which it is in a specific moment
and the influence of that sign on an individual depending on how the
zodiac was configured at the moment of his/her birth or at the moment of
asking a question to the astrologist); he also gives dignities, prelacies,
and the favour of friends and foes, and can metamorphose a man into
any shape.

According to other demonologists, Orias knows and teaches all forms of
divination, and is the protector of astrologists and diviners.

He is depicted as a lion with the tail of a serpent or a man with the face
of a lion, holding two hissing serpents in his right hand, and riding a
horse. Other depictions show him as a man with serpents instead of
legs, carrying two snakes, one in each hand, and riding a mule.
